Think about it: Tessa Janecke is the only Olympic-level player on her team. She's not surrounded by other players who are at that level, at a program already at or near the top, enjoying a loaded roster. If she wants to win games and elevate the Penn State program, she knows that won't happen by worrying about getting "eye popping numbers" for herself. She doesn't get to play that game. Instead, to win games, she's had to make everyone around her be a better player, too, and she's done that. Take Janecke away and put the best player from Wisconsin, Minnesota, or Ohio State on the Penn State roster, and their numbers wouldn't be eye popping, either. At a program level, she is very much a generational player, and that's probably how Jeff Kampersal meant that.
Janecke has said that she chose Penn State over Wisconsin or Minnesota because she wanted to make a program better than when she got there. That's been her motivation - not gaudy numbers. She's played her game exactly the way she's needed to play it to make the program better, and she's done it with no other Olympic-level players skating alongside her.
